The value is
Step-by-step explanation:
From the question we are told that
The mean of Jo cows is
The standard deviation of Jo cow is
The mean of Val cows is
The standard deviation of Val cows is
The sample size for both Val and Jo is n = 25
Let assume that the level of significance is
Generally from the normal distribution table the critical value of is
Generally the margin of error is mathematically represented as
Hence margin of error for Jo is
=>

Answer:31
Step-by-step explanation: take all of the odd numbers between 16 and 47. To find the mean, or average, you add up all of your numbers and divide that number by how many numbers you started with. all of the odd numbers added together=465. divide that by the 15 odd numbers(divide by 15) and then you have your average.
Answer:
<h2>12</h2>
Step-by-step explanation:
So our equation is:
(7x+5)+(5x+3)+(12x-20) = 276
First remove parenthesis:
7x+5+5x+3+12x-20=276
Combine like terms:
24x-12 = 276
Add 12 on both sides:
24x = 288
Divide:
288/24 = 12
